what fuel???? 87,89,90,91,92,93,94,...?

what octane do you guys use in your Mach's. a budy of mine just picked an '03, but we're reluctant to just trust the dealer (they said only run 87). I recommended 93+ (readily available here in WI) and am looking for additional input.

Well, it says right on the gauge cluster "premium unleaded only" so, 91 or 93.

Yeah, run the 87 and then go to the dealer with the check for the rebuild.

Damn dealers are dumb.
